SEQlite lightweight chromoly and alloy mountain bike and road bike cassettes

Wide range cassettes and drivetrain systems were pretty big at Taipei, and SEQlite had a killer offering alongside standard and narrow range road cassettes that were impressively lightweight, heavily machined and made from an assortment of metals.

Above, the wide MTB Racing Cassette uses a one-piece chromoly cluster for most of the gears with a 7075 aluminum upper cluster of three gears to save a bit of weight. They’re available in both 10- and 11-speed versions, both of which fit on a standard Shimano 10-speed freehub body.

Shift down for all the details and options…

There’s also a chromoly 11-tooth cog that caps things off on the MTB cassette.  Weights are claimed at 255g for the 11-40 (10spd), 265g for the 11-42 (10spd) and 280g for the 11-42 (11spd). We brought home a 10-speed cassette for review and it came in right on target on our scale.

Besides the alloy upper cluster, one of the key differentiators for SEQlite’s cassettes is a composite support section on the backside of the main chromoly cluster. It’s also used on the chromoly road cassette and adds rigidity to the structure by keeping multiple cogs held in position.

Some of the other cassettes are all metal. Chromoly road cassette weights are 155g to 170g, but the full titanium ones come in as light as 100g!

Like the Edco model, SEQlite also makes a narrow range 14-28 cassette for junior racers (or whoever).

When you want to get really light, there’s full 6/4 titanium cassettes and full 7075AL cassettes. If you’re thinking the titanium ones are light at 100g, the alloy model goes as low as 91g! They also make alloy mountain bike cassettes in 11-32/34/26 options that are just over 150g…but note the warning about being disposable. (We’ve requested pricing and will update this post as soon as we hear back).

This little 9/10/11 tooth adapter is made to fit Shimano’s Capreo hubs, which are surprisingly similar to SRAM’s XD Driver Body…except they came first, and they were really just designed to allow for super small cogs.

Care to share the tooth counts of the 11-40 ten-speed cassette?

Great to see more big cassettes coming out. The add on 40t and 42t cogs were great but its time to make a purpose built cassette, it seems like a waste to buy a cassette and just trash two new cogs. I’m sure these will be pricey since they’re light. I’m expecting cheaper/heavy stuff to come out soon for general riding.

Obviously the machining is what makes them expensive but I’m still surprised nobody is making an after market cassette for a SRAM system yet. I can’t see anything being under $150 anytime soon but I think something around $200 or lower is possible, maybe in two parts so you can replace sections of the cassette?

Not only was the Capreo designed/released first, but it’s also not technically rated for MTB use, which is actually fine because there is no 12×142 option, let alone a disc hub option.

to add to what @Seraph already pointed out, Capreo was designed for the small-wheeled bike niche (think Birdy, Bike Friday, and folding bikes), not off-road applications. At least one company did try to make a go of making Capreo-style cassettes work for mtb…maybe not much heard since(?)

The seqlite 11-36 full race 7075al cassette is about £90 if you can find one.
Machining finish isn’t much to shout about, mine still had some small swarf left over from what I expect is a blunt head.
They are pure race only though.
I started seeing tooth deformation at the chain loading points after 1 non-hard ride.
Switched to x0 instead as don’t have money to burn!
Might bring it out again for a race day if I’m feeling lucky.

canfield had the 10speed hub with capreo-style freehub and a custom 10speed cassette.

you can buy a dt swiss 240 etc. compatible capreo-style freehub body from any specialized dealer. they used this custom piece for the s-works demo.

Be sure to verify the tooth sizes with SeqLite.
Their 12-27 road cassettes end with 23-25-27, where a 2-tooth difference at the big end is almost worthless, esp. when the 15-17 step is also 2 teeth diff.

Considering IRD is charging $220.00 for some shitty boat anchor 11-42 10 speed cassette I can only imagine what these are going to cost.

@Seraph: Canfield Brothers Microdrive hubs uses the Capreo standard.

Got it on my DH bike. 12X150mm and disc. 12X142 is available too I belive. Works great for gaining a little more ground clearance on my cranks (9tX30t equals roughly 11tX36t and gives me ca 1cm extra). Win!

I love that Capreo option. Canfield Brothers had a hub that was 142×12 compatible. I’m using it but am very disappointed because they stopped supplying those parts. They said they are not able to get the gears any more. I hope we can somehow find a way to get the gears because I love that set up. I’m currently running a 9-40 cassette on my mountain bike.

If you want some rear world feedback, I bought a few sets of these in 2014 at the show. On both cassettes, teeth sheared off under normal use and rendered them unusable. Honestly would not recommend.
